Tour the Upper East Side penthouse where Sinatra used to host wild ragers with his Rat Pack

Architect Marvin Mitchell has bought Frank Sinatra's former penthouse at the Edgewater building on 530 E. 72nd Street for a cool $4.995 million.

Mitchell - who told The Wall Street Journal that he purchased the home for its spacious floorplan, not its history - takes ownership of the 3,200-square-foot, tri-level apartment just four years after the previous owner, Long Island car insurance executive Penny Hart, renovated it. Hart, who bought the home for a reported $2.5 million and never lived in it, first listed it at $7.7 million in 2012.
